I have a sedevacantist, Traditional latin mass, non diocese affiliated church near me. Sister i talked to maintains all other religions are destined for hell, even Lutherans.
Im open to a conversion but idk. Imo Jesus doesnt need the middleman but ive been wrong before.
The only person truly responsible for living in christ conciousness is you. A lot of religous leaders care as much for your personal spiritual sovereignty as a used car salesman cares that you get a 'great car'.
Of course many can help you along your journey, but the christ message is that the individual is ultimately responsible.
